Thread: radio/hdradio/obdII testing in nghost

Okay, I hooked my tuner directly to the serial port on my docking station, and still no control or audio. I didn't find those configuration files for the hdradio tuner installed anywhere, so, I'll need to know where to put them.

Looks like the plugin looks in /etc/HDRadio.cfg and the default serial port is ttyS0:

Code:

mainconfigfile="/etc/HDRadio.cfg";
	sessionconfigfile = getenv("HOME");
	sessionconfigfile += "/.hdradio/HDRadioSession.cfg";
//DEBUG: Remove the following 2 lines when we're done testing.
// 	mainconfigfile = "hdradio/HDRadio.cfg";
// 	sessionconfigfile = "hdradio/HDRadioSession.cfg";
	defaultserial = "/dev/ttyS0";

Okay, I found the config files and moved them to their proper places.

I ran nghost again and I still don't have control of the tuner.

Note: When the hdradio tuner is plugged into power, line-in and serial, I get static whether nghost is running or not.

Currently, I'm using my ThinkPad's docking station serial port, /dev/ttyS0. I made one change to the hdradio.cfg file in /etc/ opting to turn the detection feature on.

The hdradio session config file is located in /home/user/.hdradio.

When nghost runs, I find no errors related to the serial port or operation of the hdradio plugin itself.

So, what next?

can you confirm the plugin is running at all? I don't remember if I mentioned that you need to add "libhdradio" (or "libnhdradio"?) to your ~/.nghost/plugins.conf ?

try:

nghost -d4 -lstdout | grep radio

No, you did not mention the fact that I needed plugins.conf, so I added it. After creating a plugins.conf file with the single entry libnhdradio, nghost will not load. The following is the output:

nghost

However, running the command nghost -d4 -lstdout | grep radio got the library working! Clicking on presets work, seek works. I can tune in stations. However, I have no working indicators; no frequency or RDS data is displayed. The hdradio tuner does mute when I quite nghost.

Here is the output when I run the above command and nghost initially loads. You can also hear the tuner come on but stay muted:

Correction: I do have a frequency indication, and RDS does output but not correctly. There is one radio station that has RDS and what I get displayed is just the characters %s: %s. I should point out that I have a poor antenna--a short rubber duck type antenna and a bit of wire connecting it to the tuner.

Another observation: I have no audio until I click on one of the preset buttons, then I can tune and use the radio.

so it works if you run nghost -d4 but not when you run "nghost" (noargs)?

That's good you got it somewhat working. We'll take a look at your issues.

Thanks!

I have a minor update. After shutting down and rebooting the system, using nghost without the debug command will load nghost without any crashes. Otherwise, the plugin behavior is the same.
